GARBURETER MECHANISM.

Specification of Letters Patent.

Patented Sept. 9, 1913.

Application filed May 29, 1913. Serial No. 770,680.

To all whom it may concern:

Be it known that I, MILTON L. SAMMONS, a-citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented a certain new and useful Improvement in Carbureter Mechanisms, of which the following is a specification.

My invention relates to improvements. in

carburetor mechanisms.

It is particularly adapted for use in connection with carbureters of explosive engines employed for propelling automobiles.

Considerable difliculty is experienced in 1 the operation of explosive engines at high altitudes, due to the rarefied condition of the air and to lack of moisture in the air.

One of the objects of my invention is to provide a sim 1e and eflicient mechanism for economical y mixing water vapor with air prior to its introduction into the carbureting chamber of a carbureter, so as to increase the efficiency of the engine.

A further ob'ect of my invention is to provide a simple, eflicient and economical mechanism for heating the carbureting chamber of a carbureter, so as to increase its efliciency.

A further object of my invention is the provision of novel mechanism for bringing into cooperative relationship with each other, the mechanism controlling the opera tion of the carburetor, and the mechanisms which convert water into vapor and steam for respectively vaporizing the air used in the carbureter and for heating the carbureting chamber of the carbureter.

Other novel features of my invention are hereinafter fully described and claimed.

In the accompanying drawings which illustrate the preferred form of my inventionFigure 1 is a side elevation showing my improved mechanism applied to a sixcylinder explosive engine, some of the parts being broken away. Fig. 2 is a vertical sectional view on the line (Tr-b of Fig. 1. Fig. 3 is a side elevation showing my invention applied to a six-cylinder engine, the view being taken at the opposite side of the 0 engine from that of Fig. 1. Fig. 4 is a vertical section on the line -od of Fig. 2. Fig. 5 is a vertical section, enlarged on the line e f of Fi 2.

Similar ref erence characters designate similar parts in the difi'erent views.

Referring particularly to Fig. 5 1 designates the carbureting chamber 0 a carbureter, which is provided with an air inlet 2, with which connects a conductor 3, having its opposite end mounted in a hole provided in the bottom of a horizontal tube 4, which encircles and is spaced apart from a manifold exhaust pipe 5, connected with the cylinders 6, of the explosive engine. The ends of the tube 4 are open to the atmosphere. The space between the tube 4 and the pipe 5 forms a chamber 7 for the commingling of air and water vapor.

For producing the vaporwhich is to be mixed with the air, there is provided above the engine a water tank 8, with which is connected one end of a water conductor 9, which, at its other end, is provided with a horizontal portion, which is mounted in a longitudinal slot in the upper side of the tube 4, and which is disposed parallel with the exhaust pipe 5, and is provided in its lower side with a plurality of openings 10 which discharge into the chamber 7 against the pipe 5 and through a wire screen 11, which is of channel form and located longitudinally in the chamber 7 Forming a part of the conductor 9, is a valve casin 12, in which is mounted a shutoif valve 0 the ordinary type and which is provided with a crank arm 13, to which is connected one end of a rod 14, the other end of which is secured to a crank arm 15, which is secured to a horizontal rock shaft 16, pivotally mounted in bearings 17 which are supported in any suitable manner, as by means of the central cylinder 6. The rock shaft 16 has secured to it a crank arm 18, the upper end of which is bifurcated and embraces a forwardly and rearwardly extending operating rod 19, which at one end is pivotally connected to a crank arm 20, which is secured to a pivot stem 21, of a butterfly valve 22, which is mounted in the carbureter chamber 1, and which controls the discharge of the explosive mixture through the outlet 23 of said chamber. Two collars 24, are mounted on the rod 19, at opposite sides of the crank arm 18. The forward end of the rod 19, is connected to one arm of a bell crank lever 25, the other arm of which is connected to the lower,end of a'rod 26, whichhas its upper end connected to a pedal 27.

Encircling the exhaust pipe 5 is a hollow '110 cylinder 28, having closed ends and forming with the pipe 5, an annular chamber 29, with which communicates one end of a conductor 30, having its other end communicating with an annular chamber 31, which encircles the chamber 1, as shown in Fig. 5. Said annular chamber 31 is provided with an outlet 32.

Forming a part of the conductor 33, which is connected to the tank 8, and which has a horizontal portion located in a slot in the. top of the cylinder 28, is a valve casing 34, provided with a shut-off valve having a crank arm 35, pivoted to one end of a rod 36, the othercnd of which is pivoted to a crank arm 37, which is secured to the 'rock shaft 16. The horizontal portion of the conductor 33 is provided in its lower side xwith dischar e openings 38, disposed so as to discharge 1nto the chamber 29 and against the exhaust pipe 5.

Communicating with the air inlet 2, as shown in Fig. 5, is a vertical air pipe 39, into which extends a pipe 40, which is connected with a liquid fuel tank, not shown.

The arrangement of the valves in the easings 12 and 34, and the valve 22, is such that when the pedal 27 is depressed and the rod 19 moved forwardly, the shaft 16 will be rocked so as to simultaneously open the valves in the casings 12 and 34, at the same time that the butterfly valve 22 is opened. A spring 41, may be provided to retract the bell crank lever 25, and through it the rod 19, so as to close the butterfly valve 22, and the valves within the casings 12 and 34, by the mechanism already described.

When the valves 12 and 34 are opened, the water will pass from the tank 8. throu h the conductors!) and 33 respectively, an into the chambers 7 and 29. The water entering the chamber 7, will pass through the screen 11, which will serve to diffuse the water over the pipe 5, the heat from which will vaporize the water which in this form will mix with the'airentering at the end of tube 4, the mixed air and vapor passing from the chamber 7 by way of the conductor 3, into and through the inlet 2 and pipe'39. The mixture will intermingle with the liquid fuel which is discharged from the pipe 40. The presence of the water vapor .wlll increase the efliciency of the explosive mix ture. The water passing through the conductor 33 will be converted into steam in the chamber 29, due to the heat of the pipe 5, and passing from said chamber into the annular chamber 31, through the conductor 30, will heat the chamber 1, thereby adding to the efliciency of the explosive mixture.

It will be noted that when the butterfly valve 22 is closed no water will ass from n the tank 8 through the conductors 9 and will be partly opened. Thus the amount of water which is discharged from the tank 8 through the conductors 9 and 33, will be proportlonat'e to the amount of fuel burned, and when the carbureter is not in operation no water will pass from the tank 8.

I do not limit my invention to the structure described and illustrated, as modifica tions, within the scope of the appended claims, may be made without departing from the spirit of my invention.
